The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>
A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.
In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:
![Z=\frac{x\;-\;u}{\delta}](https://tex.z-dn.net/?f=Z%3D%5Cfrac%7Bx%5C%3B-%5C%3Bu%7D%7B%5Cdelta%7D)
<u>Where:</u>
- x is the observed data or sample mean.
is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.

Answer:
x = 16
Step-by-step explanation:
m<B+m<C+m<D = 180°
5x + 14 + x + 19 + 2x + 19 = 180
8x + 52 = 180
8x = 180 - 52
x = 128/8
x = 16
Answer:
y = x+5 This equation satisfies all the four sets of x and y values 1.When x = 5,y = x+5 = 5+5 = 10 2.When x = 10,y = x+5 = 10+5 = 15 3.When x =15,y = x+5 = 15+5 = 20 4.When x = 20,y = x+5 = 20+5 = 25 Hence,

Let's assume
x is number of hours worked
y is amount paid
Since, this is linear relationship
We can select any two points
(2,36.50) and (4,73)
so, we can also write as
x1=2 , y1 =36.50
x2=4 , y2=73
Firstly, we can find slope
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
we can plug values
![m=\frac{73-36.50}{4-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B73-36.50%7D%7B4-2%7D)
![m=18.25](https://tex.z-dn.net/?f=m%3D18.25)
now, we can use point slope form of line
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
we can plug values
![y-36.50=18.25(x-2)](https://tex.z-dn.net/?f=y-36.50%3D18.25%28x-2%29)
now, we can solve for y
![y=18.25x](https://tex.z-dn.net/?f=y%3D18.25x)
